Re: [EnergyPlus_Support] Zone Multipliers hate Daylighting Controls!!!





I don't know this for a fact, but I suspect that you can multiply floors but not windows

Dear group,

Is my interpretation correct? because the following error message appeared after I added daylighting controls to zones in a typical floor to which I applied a zone multiplier value.

** Severe  ** DayltgAveInteriorReflectance: Multiplier > 1.0 for window 1A2A3F:F17OFFICEOPENPLAN_WALL_7_0_0_1_0_1_WIN in Zone=1A2A3F:F17OFFICEOPENPLAN

   **   ~~~   ** ...not allowed since it is in a zone with daylighting.

   **  Fatal  ** Progrem terminates due to preceding conditions.

   ...Summary of Errors that led to program termination:

   ..... Reference severe error count=1

   ..... Last severe error=DayltgAveInteriorReflectance: Multiplier > 1.0 for window 1A2A3F:F17OFFICEOPENPLAN_WALL_7_0_0_1_0_1_WIN in Zone=1A2A3F:F17OFFICEOPENPLAN

   ************* Warning:  Node connection errors not checked - most system input has not been read (see previous warning).

If E+ cannot model daylighting controls for zones with multipliers, then it will be really difficult to deal with high rise buildings for which there is a high number of typical floors with daylighting controls!

Please advise.
